2007-03-27V4L/DVB (5441): Saa7146: Fix allocation of clipping memoryOliver Endriss
Olaf Hering pointed out that SAA7146_CLIPPING_MEM would become very large for PAGE_SIZE > 4K. In fact, the number of clipping windows is limited to 16, and calculate_clipping_registers_rect() does not use more than 256 bytes. SAA7146_CLIPPING_MEM adjusted accordingly.

2007-03-01V4L/DVB (5304): Improve chip matching in v4l2_registerHans Verkuil

2007-02-21V4L/DVB (5147): Make vivi driver to use vmalloced pointersMauro Carvalho Chehab
Before this patch, vivi were simulating a scatter gather DMA transfer. While this is academic, showing how stuff really works on a real PCI device, this means a non-optimized code. There are only two memory models that vivi implements: 1) kernel alloced memory. This is also used by read() method. On this case, a vmalloc32 buffer is allocated at kernel; 2) userspace allocated memory. This is used by most userspace apps. video-buf will store this pointer. a simple copy_to_user is enough to transfer data. The third memory model scenario supported by video-buf is overlay mode. This model is not implemented on vivi and unlikely to be implemented on newer drivers, since now, most userspace apps do some post-processing (like de-interlacing). After this patch, some cleanups may be done at video-buf.c to avoid allocating pages, when the driver doesn't need a PCI buffer. This is the case of vivi and usb drivers.

2007-02-21V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-12-10V4L/DVB (4879): budget-ci IR: integrate with ir-commonDavid Hardeman
This converts the budget-ci driver so that it uses ir-common for some of its IR processing. In particular, the keymap for the Nova-T (sub 13c2:1011) is switched to the Hauppauge grey/black keymap, of which the keys on the supplied R808 remote control form a subset. The old budget-ci keymap is moved to ir-keymaps.c and is used for other remotes. The debounce logic for buggy remotes (i.e. Zenith) is made conditional the new debounce parameter and defaults to off (so that repeat keypresses aren't ignored for all working remotes). Some parts are based on Darren Salt's dvb-ir patchset.

2006-12-10V4L/DVB (4861): Remove the need of a STD array for drivers using video_ioctl2Mauro Carvalho Chehab
video_ioctl2 will auto-generate standard entries at ENUM_FMT. Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std.

All radio devices use an obsolete mode of opening/release driver.

2006-09-10V4L/DVB (4605): Fixes an issue with V4L1 and make headers-installMauro Carvalho Chehab
V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined, to allow checking for broken V4L2 ports. This is very important during the migration phase for V4L2 API. However, userspace apps should be capable of using both APIs, since they need to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when __KERNEL__ is not defined, those ioctls and corresponding structs should be visible. This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT and CONFIG_VIDEO_V4L2.

Move the check from bttv-driver.c into v4l2-dev.h, because all other callers of video_device_create_file must also be checked. Replace the call to class_device_create_file in videodev.c with video_device_create_file, as defined in v4l2-dev.h, so that the return value of class_device_create_file will be checked.
